LSX454 swapped 95 BASS burb.

Gotta find the weak link sooner or later!

Can we quote you on that? I thinking of when the Vette gets back to the track again.

 

[shady]

Finding the weak link just lets you know what to upgrade next lol.

She sounds good and looked like it did a good rip. I want to build a big LS or a big block for my truck. This is inspiration.

 

[JoshHefnerX]

I didn't see any shaking in that video. I think you were just driving it wrong... lol

Git sum!

 

[shady]

It was a good one.
Would have been better if I'd have NOT left It in 3rd.
Worked out though.

 

[shady]

Got the trans grunt on vid.
First vid at :04.
Second vid at :06

2nd vid didn't sound good. How's the fluid looking?

 

[shady]

Still looks red.
And it never really slips like a trans normally would.
It'll still shift and chirp em kinda. It just makes that sound when it does lol.

 

[folkenheath]

What happened at 2 sec in the 2nd vid?

 

[shady]

Really , I don't know.
I was trying to look for cops and hold my phone up. So I didn't catch that enough to remember it.

 

[Blue85]

Could something just be rubbing, like a header tube on the frame or some other lost clearance from motor mount flex?

 

[shady]

It only does it on the 1-2 shift .
The same shift that used to jerk the whole truck like an explosion.
Now it shifts fast and solid, but not exclusively, and it makes that sound lol
I'll look when I get it on the lift this week and see if there is something though yeah..

 

[shady]

So, I pulled the pumpkin cover and did some looking.
No idea on miles since gear swap. But less than 2500 would be my guess.
Backlash is .010"
Gear pattern. And tooth condition.

Next was a play check.
There's a LOT of play in the spiders.
I'm going to check it with both tires touching the ground. Doing it in the air, holding both tires the best we could. I was getting between .050" and .100" ring gear movement before it tries to turn the wheels. By turning the drive shaft.
Didn't vid that part.

Next was tail shaft play.
More than I would like of that too. But Im not sure, and it doesn't leak

[shady]

Shock mounts have torn up outer rings. But the weight of the axle is hanging on them right now, and the bolts are still centered.

 

[shady]

Forgot the magnet pic.
This was taken as soon as I pulled the cover.

 

[centexk5]

Those bushings are gnarly. I'd definitely recommend changing those out. Sitting static versus having to control 7k lbs is two different environments.

 

[Babaganoosh]

QA1 adjustable's should do the trick.

 

[shady]

Surprisingly they aren't old. No idea why they did that.

 

[centexk5]

Surprisingly they aren't old. No idea why they did that.

That’s sarcasm. Gotta be.
